![]() ![]() Adjustment for potential confounders lowers the risk estimate, however, many studies over adjust, such as controlling for birthweight, resulting in an inappropriate low estimate of the risk.Įpidemiologically it is difficult to distinguish the effect of active maternal smoking during pregnancy from involuntary postnatal tobacco smoking of the infant to smoking by the mother. The pooled unadjusted relative risk (RR) from these studies is almost five, which suggests that infants of mothers that smoke have almost a five times risk of SIDS compared with infants of mothers who do not smoke. Since the reduction in the prevalence of prone sleeping position there have been eight studies examining maternal smoking and SIDS. There have been almost 50 studies that have examined this relationship and all indicate an increased risk. There is substantial evidence to conclude that maternal smoking caused a marked increase in SIDS. The only babies we do not recommend back sleeping position are those with congenital abnormalities of the jaw, such as the Pierre Robin anomaly. There has been no increase in deaths from aspiration since the change in sleep position. Deaths from such causes are rare in countries that traditionally use the back sleeping position. The major concern about the back sleeping position was the perceived danger of aspiration of vomit. More recent studies have shown that the risk of SIDS with the side sleeping position is about twice that of infants sleeping on their back, probably because the side sleeping position is relatively unstable, and some babies turn to the prone position. The most compelling evidence that prone sleeping position (front sleeping) is causally related to SIDS comes from the major reduction in SIDS rates in the last decade in many countries following prevention programmes changing infants from the prone sleeping position onto their sides or backs. What is the evidence for this advice? Sleep positionĮpidemiological studies in several countries have identified prone sleeping position as an important risk factor for SIDS. If you smoke or smoked during pregnancy, sleep your baby in its own bed.Have a smoke-free pregnancy and smoke free home.The current advice of the New Zealand Cot Death Association to help prevent SIDS is: And finally the baby needs to be exposed to some stress, such as prone (front) sleeping position. The baby must be predisposed, such as having an arousal defect, which may have been caused by the effects of tobacco smoke when in the uterus. What causes SIDS?Īlthough we don't know for certain, the most likely explanation is that a combination of factors affects a baby at a critical stage of development. ![]() ![]() Babies can die suddenly and unexpectedly in prams, cars, beds or even someone's arms. SIDS can occur anywhere - not just in the cot. The jagged barb firmly secures 3/16″ ID sample tubing to the stem of the valve.Īll sampling instructions above are recommended guidelines for OSHA Compliance Safety and Health Officers (CSHOs), please see the corresponding OSHA method reference for complete details.Sudden Infant Death Syndrome (SIDS or cot death) is defined as "The sudden death of an infant or young child, which is unexpected by history, and in which a full postmortem examination fails to demonstrate an adequate cause of death." The nickel-plated brass connection allows the user to control gas flow into or out of the bag by twisting the barbed stem open (counterclockwise) or closed (clockwise). *Note for sampling with Cali-5-BondTM, 10 liter, five layer aluminized gas sampling bag: This gas sampling bag has an integrated twist on/off valve (V-NPB-2/00) Septum (A-SEPT/.750). If greater than PEL, order gas sampling bags. ![]()
